Reaction Steps

To a solution of the compound of 3-(2-pyridyl)-phenyl acetic acid methyl ester (3.8 g, 16.7 mmol) in THF (50 mL) was added a solution of LiOH.H2O (780.2 mg, 18.6 mmol) in H2O (10 mL). The reaction was stirred at room temperature until TLC analysis indicated the complete consumption of starting material (2 h). The reaction mixture was concentrated to remove THF, then neutralized to pH=7 by the addition of IN HCl, diluted with brine (50 mL), and washed with CHCl3 (100 mL) The aqueous layer was readjusted back to pH=7 by the addition on IN NaOH and washed with fresh CHCl3 (100 mL). After repeating this procedure once more, the organic layers were combined, dried, filtered (MgSO4) and concentrated to give 3.79 g of the title compound: MS (ES+) 214.3 (MH+).
